https://sensationsenglish.com/Built and evolved Sensations English, a video-based English learning platform that teaches learners through authentic news and cultural content adapted across five CEFR levels, from A1 to C1.
I led the technical architecture and development across its learning and institutional ecosystem.
Key contributions included:
• Architected four connected portals for students, schools and universities, affiliates, and platform administrators.
• Built CEFR-based video learning workflows with level-specific transcripts, vocabulary, quizzes, and progress tracking.
• Developed virtual classrooms, coursework assignments, student rosters, gradebooks, and institutional license management.
• Implemented the Node.js, Express, EJS, and MySQL architecture with authentication, subscriptions, analytics, and video delivery.
• Led ongoing technical decisions, feature development, releases, and engineering guidance.
The platform grew to 50,000+ users and supports both individual learners and educational institutions.

IoT Proximity and Workforce Automation Platform
https://www.eigent.com/Built and evolved Blitzl, an IoT and location-intelligence platform that uses Bluetooth Low Energy beacons and GPS geofencing to automate workforce attendance, coordinate curbside pickups, and support real-time safety alerts.
I led mobile development across native iOS and Android, focusing on reliable background location and hardware communication.
Key contributions included:
• Built BLE beacon scanning and ranging using CoreBluetooth, iBeacon, and Android Bluetooth APIs.
• Developed geofenced workforce attendance with automatic clock-in/out and safeguards against false location events.
• Integrated physical BLE panic buttons with SOS alerts and live GPS location sharing.
• Built proximity-aware curbside pickup workflows that detect customer arrival and notify store staff.
• Optimized background execution, offline synchronization, battery usage, and location accuracy across iOS and Android.
The platform combined BLE hardware, geofencing, real-time communication, and native mobile engineering into a single proximity-aware system.
